Zhang, H. (author), Dabironezare, Shahab Oddin (author), Llombart, Nuria (author)Lens based focal plane arrays (FPAs) with thousand elements are promising candidates for wide scanning sub-millimeter security imaging systems. To analyze such arrays, a field correlation approach is employed to design an FPA of quartz lenses coupled to a reflector. We consider quartz as the lens material due to its lower cost compared to...conference paper 2023

(author), Ferrari, Lorenza (author), Murugesan, Vignesh (author), Thoen, David (author), Dabironezare, Shahab Oddin (author), Zhang, H. (author), Llombart, Nuria (author), Baselmans, J.J.A. (author)A focal plane array of extended-hemispherical silicon lenses coupled to aluminum coplanar-waveguide (CPW) Microwave Kinetic Inductance Detectors (MKIDs) has been designed to operate at 7.8 THz. Low-dispersive leaky-wave radiation has been used to efficiently illuminate the antireflection-coated lenses. To minimize the radiation loss from the...conference paper 2022

Zhang, H. (author), Dabironezare, Shahab Oddin (author), Carluccio, G. (author), Neto, A. (author), Llombart, Nuria (author)In this work, a free accessible MATLAB interface is presented to analyze antenna-coupled Quasi-Optical (QO) systems in reception. This goal is achieved by using Fourier Optics (FO) and Geometrical Optics (GO) based methods. Specifically, the FO method represents the field focalized by a QO component on its focal plane as a plane wave spectrum...conference paper 2019
